Cloudy container pond

[SBellew]

I changed the water in my container pond after the last cold snap in AL and the water was nice and pretty until about 2 days later then BAM! cloudiness. What can I do to resolve this issue. I did not have this problem last year when I set it up initially and went through the same process this time as last year when setting it up with chemicals, pump, fish, etc.

Here is my pond from setup last July:

I noticed today that the water is actually a greenish tint and not just cloudy from like sediment and such. Guess I need to read up on getting rid of algae.

just out of curiosity how large is this container?

Its a 35 gallon pond kit from Lowes.

My plant is starting to put out new leaves and it is helping a bit. I am also taking out about 5 gallons a week and replacing it with fresh water.
